摘　　要：以南京市三山桥的设计为研究对象,阐述自锚上承式拱桥的结构构思,研究预应力筋和矢跨比2个关键因素对自锚上承式拱桥拱脚推力的影响,介绍自锚上承式拱桥的预应力筋的优化设计方法。实桥测试结果表明,该设计是可行的。Taking the design of Sanshan Bridge in Nanjing City as the study object, this paper describes the considerations of structural formation of the self-anchored deck arch bridge and makes a study of the influence of two critical factors of the prestressing tendons and rise-to-span ratio on the thrust of arch springs of the type of the bridge. In addition, the paper also presents the optimal design method for the prestressing tendons of the bridge. The results of testing in the filed prove that the design method as mentioned is feasible.

关 键 词：自锚上承式拱桥 自锚预应力 矢跨比 优化设计 桥梁设计
